4.5. UPS OPERATING MODES.
Normal mode.
•
Device running supplying output voltage from the inverter.
Mains power present with correct input voltage and frequency.
Battery mode.
•
Device running with mains voltage or frequency out of range
or without AC input power, either due to mains failure or
absence of cable connection, supplying output voltage from
the batteries.
Bypass mode.
•
Device running or not, supplying output voltage directly from
the AC mains.
With the inverter running, this operating mode may be due
to an overload, blockage or inverter fault.
The actions for each incident will be as follows: Reduce
the load connected to the output, unblock the device by
resetting it – stop it and start it up again – and, if the
blockage or fault remains, contact T.S.S.
With the inverter shut down, the output supplies mains
power directly through the static bypass of the device
provided that it has AC input power.
Frequency converter (CF) mode.
•
Operating mode of the UPS as a frequency converter. In this
mode, the static bypass is disabled by the condition of dispa-
rate input and output frequencies.
Even if the LCD display on the backlit control panel shows
messages, it does not mean that the inverter is opera-
tional. It is switched on by pressing the "ON" button on the
control panel, see Chapter 6.
4.5.1. Notable features.
True on-line with double-conversion technology and output
•
frequency separate from the mains.
Output 1 power factor. Pure sine waveform, suitable for almost
•
all kinds of loads.
Input power factor > 0.99 and high overall performance be-
•
tween 0.89 and 0.91. Greater energy savings and lower user
installation costs (wiring), as well as low distortion of the input
current, which reduces pollution in the power supply network.
Great adaptability to the worst conditions of the mains. Wide
•
input voltage, frequency and waveform ranges, thus avoiding
excessive dependence on limited battery power.
Possibility of fast and easy backup extension by adding mod-
•
ules in rack format. Each battery module has two connectors
for easy connection to the device and other identical modules.
Availability of battery chargers of up to 6 A to reduce battery
•
recharge times.
Selectable high-performance mode (ECO MODE) > 0.95 to
•
0.99 depending on model. Energy savings, economically
beneficial for the user.
48
Possibility of starting the device without mains power supply
•
or discharged battery. Be careful with this aspect because the
greater the batteries are discharged, the more the backup will
be reduced.
Intelligent battery management technology is very useful for
•
extending the life of accumulators and optimising recharge
times.
Standard communication options via the RS232 serial port or
•
USB port.
Remote Power Off (RPO).
•
Control panel with LCD display available on all models
•
and LED.
Availability of optional connectability cards to improve commu-
•
nication capabilities.
Device that can be installed as a tower or rack using the
•
accessories supplied. The control panel can be rotated to
adapt to either format.

4.6. OPTIONS.
Depending on the configuration chosen, the device may include
any of the following options:
4.6.1. Exterior manual maintenance bypass.
The purpose of this option is to electrically isolate the device from
the mains and the critical loads without cutting the power to the
latter. In this way, maintenance or repair operations on the device
can be carried out without interruptions to the power supply of the
protected system, while preventing unnecessary hazards for the
technical personnel.
4.6.2. Communication card.
The UPS features a slot at the rear for inserting one of the following
communication cards.
Type
Input/output type
Single-phase / Single-phase.
